azure - 关于在 Azure 应用服务上托管的 D :\local\Temp in .Net 6 Web API 上可用空间不足的异常(即使有大量空间)

我有一个在 Azure 应用服务上运行的 .Net 6 Web API(Windows，标准服务计划 (S1: 1))

偶尔，我会遇到此异常:

System.IO.IOException: There is not enough space on the disk. :'D:\local\Temp\ASPNETCORE_7aca67c0-7d1f-40ba-bef3-9e58ea744487.tmp'

这是最后一次发生的堆栈跟踪:

这发生在各种 API 端点上(即各种 Controller 中的各种操作方法)。奇怪的是，它发生在我没有执行任何文件写入事件的方法中。这是一个简单的 GET 请求，它从 MySql 数据库执行基本的 SELECT * FROM table 查询，并返回结果。

现在，如果我转到 Azure 门户，然后转到我的应用程序服务，然后转到配额，我还有足够的可用空间:

如果我转到 Kudu，然后转到环境，我会看到以下内容:

D:\home usage: 51,200 MB total; 47,873 MB free
D:\local usage: 11,264 MB total; 10,894 MB free

如果你看最后两行，我在 D:\home 和 D:\local 上都有足够的空间

有什么想法吗？

最佳答案

这里好像有解释。解决方案是对请求启用缓冲。 ASP.NET CORE 将请求正文写入 Windows TEMP 文件夹

M$ 文档用于请求缓冲。 https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.http.httprequestrewindextensions.enablebuffering?view=aspnetcore-6.0
